Description
本発明は、例えば車両の前照灯等に利用される放電灯を点灯する放電灯点灯装置に関する。 The present invention relates to a discharge lamp lighting device for lighting a discharge lamp used for, for example, a vehicle headlamp.
放電灯点灯装置を構成する電子部品は、外部環境から保護するため、筐体内に組み付けられる。この筐体は、ＥＭＣ対策としてノイズシールドを行う必要があるため、アルミ等の金属材料で構成される。ただし、筐体の少なくとも一面は、電子部品を組み付ける工程の都合上、開口している。そこで、電子部品の組み付け後、筐体の開口部を金属製のカバーで覆い、そのカバーと筐体とを電気的に接続し、ノイズシールドを行う（特許文献１参照）。 The electronic parts constituting the discharge lamp lighting device are assembled in a housing in order to protect from the external environment. This casing is made of a metal material such as aluminum because it is necessary to perform noise shielding as an EMC countermeasure. However, at least one surface of the housing is opened for convenience of the process of assembling the electronic component. Therefore, after assembling the electronic component, the opening of the housing is covered with a metal cover, the cover and the housing are electrically connected, and noise shielding is performed (see Patent Document 1).
従来の放電灯点灯装置Ｐ１の具体的な構造は図５及び図６に示すものである。図５は従来の放電灯点灯装置Ｐ１の平面図である。図６は、図５におけるＡ−Ａ断面での側断面図である。 A specific structure of the conventional discharge lamp lighting device P1 is shown in FIGS. FIG. 5 is a plan view of a conventional discharge lamp lighting device P1. 6 is a side cross-sectional view taken along the line AA in FIG.
放電灯点灯装置Ｐ１は、その上側に取り付けられた放電灯Ｐ３の点灯制御を行う電子部品Ｐ５、Ｐ７、Ｐ９、Ｐ１１、Ｐ１３と、電子部品Ｐ７、Ｐ９、Ｐ１１、Ｐ１３を保持する樹脂製のケース部材Ｐ１５と、上面が開口し、ケース部材Ｐ１５を内部に収納する金属製の筐体Ｐ１７と、筐体Ｐ１７における開口部を上側から覆う金属性のカバー部材Ｐ１９とを備える。ケース部材Ｐ１５の内部には、ターミナルＰ２１が配置されており、そのターミナルＰ２１により、電子部品Ｐ５、Ｐ７、Ｐ９、Ｐ１１、Ｐ１３は相互に接続されている。 The discharge lamp lighting device P1 is an electronic component P5, P7, P9, P11, P13 that controls the lighting of the discharge lamp P3 mounted on the upper side, and a resin case that holds the electronic components P7, P9, P11, P13. A member P15, a metal casing P17 having an upper surface opened and housing the case member P15 therein, and a metallic cover member P19 covering the opening of the casing P17 from above are provided. A terminal P21 is arranged inside the case member P15, and the electronic components P5, P7, P9, P11, and P13 are connected to each other by the terminal P21.
カバー部材Ｐ１９は、その一端において、スクリュＰ２３によって筐体Ｐ１７に固定される。また、カバー部材Ｐ１９は、反対側の端部に、略くの字型の断面形状を有し、弾性変形可能なカバーＧＮＤ接点Ｐ２５を備えており、このカバーＧＮＤ接点Ｐ２５がケース部材Ｐ１５と筐体Ｐ１７との隙間Ｐ２７に挿入される。隙間Ｐ２７の幅はカバーＧＮＤ接点Ｐ２５の本来の（弾性変形していない状態における）幅より狭いため、カバーＧＮＤ接点Ｐ２５は、隙間Ｐ２７において、横方向に圧縮変形し、その反発力により、筐体Ｐ１７の内面に押し付けられる。その結果、カバー部材Ｐ１９は、その両端（スクリュＰ２３によって固定される側とカバーＧＮＤ接点Ｐ２５の側）において筐体Ｐ１７と電気的に接続し、ノイズシールドの機能を奏する。 The cover member P19 is fixed to the housing P17 at one end by a screw P23. Further, the cover member P19 has a substantially GND-shaped cross-sectional shape at the opposite end, and is provided with a cover GND contact P25 that can be elastically deformed. The cover GND contact P25 is connected to the case member P15 and the housing. It is inserted into the gap P27 with the body P17. Since the width of the gap P27 is narrower than the original width (in a state where it is not elastically deformed) of the cover GND contact P25, the cover GND contact P25 is compressed and deformed in the lateral direction in the gap P27, and the repulsive force Pressed against the inner surface of P17. As a result, the cover member P19 is electrically connected to the housing P17 at both ends thereof (the side fixed by the screw P23 and the cover GND contact P25 side), and has a function of noise shielding.
しかしながら、従来の放電灯点灯装置Ｐ１において、カバーＧＮＤ接点Ｐ２５は、高温環境下で経年変化したり、腐食したりして、筐体Ｐ１７との導電性が低下することがある。また、カバー部材Ｐ１９とケース部材Ｐ１５とが別体であること、及びカバー部材Ｐ１９の固定にスクリュＰ２３が必要であることにより、部品点数及び組立て工数が多くなってしまう。 However, in the conventional discharge lamp lighting device P1, the cover GND contact P25 may change over time or corrode in a high-temperature environment, and the conductivity with the housing P17 may decrease. Further, since the cover member P19 and the case member P15 are separate and the screw P23 is necessary for fixing the cover member P19, the number of parts and the number of assembling steps are increased.
本発明は以上の点に鑑みなされたものであり、カバー部材と筐体との導電性に関する信頼性が高く、部品点数及び組立て工数が少なくて済む放電灯点灯装置を提供することを目的とする。 The present invention has been made in view of the above points, and an object of the present invention is to provide a discharge lamp lighting device that is highly reliable with respect to the electrical conductivity between the cover member and the housing, and that requires fewer parts and less assembly steps. .
本発明の放電灯点灯装置は、放電灯の点灯制御を行う電子部品と、前記電子部品の少なくとも一部を保持するケース部材と、少なくとも一面が開口し、前記ケース部材を内部に収納する導電性の筐体と、前記筐体における前記一面を覆う導電性のカバー部材と、を備えている。前記カバー部材は、前記ケース部材と一体に形成され、前記カバー部材の外周には、外側に向けて突出する突出部が形成され、前記突出部の先端は前記筐体の内面に圧接する。 The discharge lamp lighting device according to the present invention includes an electronic component that performs lighting control of the discharge lamp, a case member that holds at least a part of the electronic component, and at least one surface that is open, and the conductive member that houses the case member therein. And a conductive cover member that covers the one surface of the casing. The cover member is formed integrally with the case member, and a protruding portion protruding outward is formed on the outer periphery of the cover member, and a tip of the protruding portion is in pressure contact with the inner surface of the casing.
本発明の放電灯点灯装置において、カバー部材は、筐体の開口部を覆い、突出部を介して筐体と電気的に接続（接地）している。よって、カバー部材により、筐体の開口部におけるノイズシールドを行うことができる。 In the discharge lamp lighting device of the present invention, the cover member covers the opening of the housing and is electrically connected (grounded) to the housing via the protruding portion. Therefore, noise shielding at the opening of the housing can be performed by the cover member.
また、カバー部材は、突出部を筐体に圧接させることで、若しくは圧接させた突出部と筐体を、例えば溶接などで接合させることで、カバー部材と筐体との間の導電性を確保する。そのため、高温環境下での経年変化や腐食等により、導電性が低下してしまうようなことがない。その結果、導電性に関する信頼性が高くなる。 In addition, the cover member ensures electrical conductivity between the cover member and the housing by pressing the projecting portion against the housing, or by joining the projecting portion and the housing that are press-contacted by, for example, welding. To do. For this reason, the electrical conductivity does not deteriorate due to aging or corrosion in a high temperature environment. As a result, reliability related to conductivity is increased.
また、本発明の放電灯点灯装置において、カバー部材はケース部材と一体に形成されている。また、カバー部材と筐体との間の導電性を確保する突出部は、カバー部材の一部である。そのため、例えば、カバー部材をケース部材に組み付ける工程、及び導電性を確保するための部材（例えば図５及び図６におけるスクリュＰ２３等）を別途組み付ける工程が必要なく、部品点数が少なくて済む。 In the discharge lamp lighting device of the present invention, the cover member is formed integrally with the case member. Moreover, the protrusion part which ensures the electroconductivity between a cover member and a housing | casing is a part of cover member. Therefore, for example, the process of assembling the cover member to the case member and the process of separately assembling a member for ensuring conductivity (for example, the screw P23 in FIGS. 5 and 6) are not required, and the number of parts can be reduced.
また、本発明の放電灯点灯装置において、突出部は筐体に圧接することで導電性を確保するので、突出部の寸法精度が必ずしも高くなくてもよい。
本発明の放電灯点灯装置において、前記カバー部材は、例えば、インサート成形により、前記ケース部材と一体に形成することができる。前記突出部としては、例えば、先端が先細りとなっている棒状部材が挙げられる。突出部の先端が先細りとなっていることにより、突出部を筐体に圧入し、それらの接続を確実にすることができる。また、前記カバー部材の形状としては、例えば、矩形形状（矩形の板状形状）が挙げられる。この場合、例えば、矩形の４辺にそれぞれ突出部を形成することができる。
Further, in the discharge lamp lighting device of the present invention, since the projecting portion ensures electrical conductivity by being pressed against the housing, the dimensional accuracy of the projecting portion is not necessarily high.
In the discharge lamp lighting device of the present invention, the cover member can be formed integrally with the case member by, for example, insert molding. Examples of the protrusion include a rod-shaped member having a tapered tip. Since the tip of the projecting portion is tapered, the projecting portion can be press-fitted into the housing and the connection between them can be ensured. Examples of the shape of the cover member include a rectangular shape (rectangular plate shape). In this case, for example, protrusions can be formed on each of the four sides of the rectangle.
本発明の実施形態を図面に基づき説明する。

Embodiments of the present invention will be described with reference to the drawings.
1. Configuration of Discharge Lamp Lighting Device 1 The configuration of the discharge lamp lighting device 1 will be described with reference to FIGS. FIG. 1 is a plan view of the discharge lamp lighting device 1. FIG. 2 is a side sectional view taken along the line AA in FIG. FIG. 3 is a plan view showing the vicinity of a later-described protrusion 19b (region B in FIG. 1) in the discharge lamp lighting device 1. FIG.
放電灯点灯装置１は、放電灯３の点灯制御を行う電子部品５、７、９、１１、１３と、電子部品７、９、１１、１３を保持するケース部材１５と、上面が開口し、ケース部材１５を内部に収納する金属（アルミ）製の筐体１７と、筐体１７における開口部を覆う金属性のカバー部材１９とを備える。 The discharge lamp lighting device 1 includes electronic parts 5, 7, 9, 11, 13 that perform lighting control of the discharge lamp 3, a case member 15 that holds the electronic parts 7, 9, 11, 13, and an upper surface that is open. A metal (aluminum) casing 17 that houses the case member 15 therein and a metallic cover member 19 that covers an opening in the casing 17 are provided.
上記放電灯３は、放電灯点灯装置１の上側に、それと一体に取り付けられている。
上記電子部品５はモジュールＩＣであり、筐体１７の底板と、ケース部材１５との間に配置されている。
The discharge lamp 3 is attached to the upper side of the discharge lamp lighting device 1 integrally therewith.
The electronic component 5 is a module IC and is disposed between the bottom plate of the housing 17 and the case member 15.
上記ケース部材１５は、樹脂から成る箱状の部材であり、電子部品７、９、１１、１３を収納する部分だけくり抜かれていて、その他の部分は樹脂で充填されている。また、ケース部材１５の内部には、真鍮製のターミナル２１が埋め込まれている。そのターミナル２１により、電子部品５、７、９、１１、１３は相互に接続されている。 The case member 15 is a box-shaped member made of resin, and is cut out only in the part that houses the electronic components 7, 9, 11, and 13, and the other part is filled with resin. A brass terminal 21 is embedded in the case member 15. The electronic components 5, 7, 9, 11, and 13 are connected to each other by the terminal 21.
上記カバー部材１９は、金属（アルミ）から成る。カバー部材１９の形状は、矩形の板である本体部１９ａと、本体部１９ａの外周端面に設けられた棒状の突出部１９ｂとから構成される。突出部１９ｂは、本体部１９ａの４辺にそれぞれ２個ずつ設けられており、外側に向けて突出している。突出部１９ｂの先端は、図３に示すように、先細りの形状となっている。さらに詳しくは、突出部１９ｂの先端における径の変化率は、先端に近づくほど小さくなっている。そのため、図３に示すように、突出部１９ｂの先端付近を側面から見ると、外側に凸の曲面となっている。 The cover member 19 is made of metal (aluminum). The shape of the cover member 19 includes a main body portion 19a that is a rectangular plate, and a rod-shaped protruding portion 19b provided on the outer peripheral end surface of the main body portion 19a.

More specifically, the change rate of the diameter at the tip of the protruding portion 19b becomes smaller as it approaches the tip. Therefore, as shown in FIG. 3, when the vicinity of the tip of the protruding portion 19b is viewed from the side surface, the curved surface is convex outward.
カバー部材１９は、インサート成形により、ケース部材１５と一体に形成されている。すなわち、カバー部材１９のうち、本体部１９ａの全体と、突出部１９ｂの根元の部分は、ケース部材１５内に埋め込まれており、突出部１９ｂの先端部が、ケース部材１５の側面から外側に突出している。カバー部材１９の上下方向における位置は、図２に示すように、電子部品７、９、１１、１３よりも上側である。また、ターミナル２１も、インサート成形により、ケース部材１５と一体に形成されている。 The cover member 19 is formed integrally with the case member 15 by insert molding. That is, of the cover member 19, the entire main body 19 a and the base of the protrusion 19 b are embedded in the case member 15, and the tip of the protrusion 19 b extends outward from the side surface of the case member 15. It protrudes. As shown in FIG. 2, the position of the cover member 19 in the vertical direction is above the electronic components 7, 9, 11, and 13. The terminal 21 is also formed integrally with the case member 15 by insert molding.
ケース部材１５を筐体１７内に収容したとき、図１及び図２に示すように、カバー部材１９の本体部１９ａは、電子部品５、７、９、１１、１３よりも上側において、筐体１７の開口部を覆う。また、カバー部材１９の突出部１９ｂは、筐体１７の側面１７ａにおける内面に圧接する。また、ターミナル２１も、ケース部材１５の側面から外側に突出しており、ターミナル２１の先端は、筐体１７の側面１７ａにおける内面に圧接する。 When the case member 15 is accommodated in the housing 17, as shown in FIGS. 1 and 2, the main body 19 a of the cover member 19 is located above the electronic components 5, 7, 9, 11, 13. 17 openings are covered. Further, the protruding portion 19 b of the cover member 19 is in pressure contact with the inner surface of the side surface 17 a of the housing 17. The terminal 21 also protrudes outward from the side surface of the case member 15, and the tip of the terminal 21 is in pressure contact with the inner surface of the side surface 17 a of the housing 17.
２．放電灯点灯装置１の電気的な概略構成
放電灯点灯装置１の電気的な概略構成を図４に示す。放電灯点灯装置１において、電子部品５、７、９、１１、１３は、図４に示すＤＣ／ＤＣコンバータ１０１、Ｈブリッジ１０３、スタータ回路１０５、制御回路１０７、及びフィルタ回路１０９、及び保護回路１１１を構成する。
2. Schematic electrical configuration of the discharge lamp lighting device 1 The electrical schematic configuration of the discharge lamp lighting device 1 is shown in FIG. In the discharge lamp lighting device 1, the electronic components 5, 7, 9, 11, and 13 include the DC / DC converter 101, the H bridge 103, the starter circuit 105, the control circuit 107, the filter circuit 109, and the protection circuit shown in FIG. 111 is configured.
上記ＤＣ／ＤＣコンバータ１０１は電源電圧を昇圧する。上記Ｈブリッジ１０３はその昇圧電圧を交流矩形波に変換し、放電灯３を点灯させる。また、上記スタータ回路１０５は、点灯始動時に必要な高電圧を発生させ、放電灯３のアークを形成し、その後安定点灯に移行させる。上記制御回路１０７は放電灯３の安定点灯の為の最適電力制御を行う。上記フィルタ回路１０９及び保護回路１１１は、電源電圧からのノイズ#除去と電源逆接やサージに対する保護を行う。 The DC / DC converter 101 boosts the power supply voltage. The H bridge 103 converts the boosted voltage into an AC rectangular wave, and turns on the discharge lamp 3. The starter circuit 105 generates a high voltage required at the start of lighting, forms an arc of the discharge lamp 3, and then shifts to stable lighting. The control circuit 107 performs optimum power control for stable lighting of the discharge lamp 3. The filter circuit 109 and the protection circuit 111 perform noise # removal from the power supply voltage and protection against reverse power connection and surge.
３．放電灯点灯装置１が奏する作用効果
（１）カバー部材１９は、筐体１７の開口部を覆い、突出部１９ｂを介して筐体１７と電気的に接続（接地）している。また、筐体１７は、ターミナル２１を介して、電子部品５、７、９、１１、１３のＧＮＤと接地している。よって、カバー部材１９により、筐体１７の開口部におけるノイズシールドを行うことができる。
（２）カバー部材１９は、突出部１９ｂを筐体１７に圧接させることで、カバー部材１９と筐体１７との間の導電性を確保する。そのため、高温環境下での経年変化や腐食等により、導電性が低下してしまうようなことがない。その結果、導電性に関する信頼性が高くなる。
（３）カバー部材１９はケース部材１５と一体に形成されている。また、カバー部材１９と筐体１７との間の導電性を確保する突出部１９ｂは、カバー部材１９の一部である。そのため、カバー部材１９をケース部材１５に組み付ける工程、及び導電性を確保するための部材を別途組み付ける工程が必要なく、部品点数が少なくて済む。
（４）突出部１９ｂは筐体１７に圧接することで導電性を確保するので、突出部１９ｂの寸法精度が必ずしも高くなくてもよい。
3. Effects of the discharge lamp lighting device 1 (1) The cover member 19 covers the opening of the housing 17 and is electrically connected (grounded) to the housing 17 via the protruding portion 19b. The housing 17 is grounded to the GND of the electronic components 5, 7, 9, 11, and 13 through the terminal 21. Therefore, noise shielding at the opening of the housing 17 can be performed by the cover member 19.
(2) The cover member 19 ensures electrical conductivity between the cover member 19 and the housing 17 by pressing the protruding portion 19 b against the housing 17. For this reason, the electrical conductivity does not deteriorate due to aging or corrosion in a high temperature environment. As a result, reliability related to conductivity is increased.
(3) The cover member 19 is formed integrally with the case member 15. Further, the protruding portion 19 b that secures conductivity between the cover member 19 and the housing 17 is a part of the cover member 19. Therefore, the process of assembling the cover member 19 to the case member 15 and the process of assembling a member for ensuring conductivity are not required, and the number of parts can be reduced.
(4) Since the projecting portion 19b ensures electrical conductivity by being pressed against the housing 17, the dimensional accuracy of the projecting portion 19b may not necessarily be high.
尚、本発明は前記実施の形態になんら限定されるものではなく、本発明を逸脱しない範囲において種々の態様で実施しうることはいうまでもない。
例えば、突出部１９ｂの先端を筐体１７の内側に圧接した状態で、突出部１９ｂと筐体１７とを溶接してもよい。この場合、突出部１９ｂを筐体１７に押し付ける力が小さくてもよい。
In addition, this invention is not limited to the said embodiment at all, and it cannot be overemphasized that it can implement with a various aspect in the range which does not deviate from this invention.
For example, the protrusion 19b and the housing 17 may be welded in a state in which the tip of the protrusion 19b is in pressure contact with the inside of the housing 17. In this case, the force which presses the protrusion part 19b against the housing | casing 17 may be small.
また、カバー部材１９とケース部材１５とを一体化する方法は、インサート成形に限定されない。例えば、ケース部材１５の上面にカバー部材１９を接着してもよい。
また、突出部１９ｂは、棒状部材には限定されない。例えば、本体部１９ａの外周端面から外側に突出する板状部材とすることができる。
Moreover, the method of integrating the cover member 19 and the case member 15 is not limited to insert molding. For example, the cover member 19 may be bonded to the upper surface of the case member 15.
Moreover, the protrusion part 19b is not limited to a rod-shaped member. For example, it can be a plate-like member protruding outward from the outer peripheral end face of the main body 19a.
また、前記実施の形態では、カバー部材１９の各辺における突出部１９ｂの数は２個であるが、これに限定されない。各辺における突出部１９ｂの数は、例えば、１、３、４、５、６、７・・・・のいずれかとすることができる。また、各辺における突出部１９ｂの数は、必ずしも等しくなくてもよい。例えば、長辺における突出部１９ｂの数を多くし、短辺における突出部１９ｂの数を少なくすることができる。 Moreover, in the said embodiment, although the number of the protrusion parts 19b in each edge | side of the cover member 19 is two, it is not limited to this. The number of protrusions 19b on each side can be any one of 1, 3, 4, 5, 6, 7,. Moreover, the number of the protrusion parts 19b in each side is not necessarily equal. For example, the number of protrusions 19b on the long side can be increased, and the number of protrusions 19b on the short side can be reduced.
また、筐体１７及びカバー部材１９の材質は、アルミ以外でも、導電性を持つ材料から適宜選択できる。例えば、アルミ以外の金属、導電性樹脂等が挙げられる。 Moreover, the material of the housing | casing 17 and the cover member 19 can be suitably selected from the material which has electroconductivity other than aluminum. For example, metals other than aluminum, conductive resins, and the like can be given.
